Answer:

The bearing of B from C is 22° counterclockwise

Step-by-step explanation:

∠CAB = 210 - 90 = 120°

Extend a line from A to the west.

drop a perpendicular line from that line to point C.

Let's call the point at the perpendicular point, M.

∠MAC = 180° - 120° = 60° because they are supplementary.

Now we have a right ∠CMA with a known hypotenuse and a known angle.

Solve for MA:

cos 60° = MA/3.8 = 1.9

Solve for MC:

sin 60° = MC/3.8 = 3.29

MB = 1.9 + 6.4 = 8.3

tan ABC = 3.29/8.3 = 21.62°

What is the solution to -4l-2x+6l=-24
Masteriza [31]

Answer:

Step-by-step explanation:

-4|-2x+6|=-24 divide both sides by -4

|-2x+6|=6 rewrite twice

-2x+6=6  and  -2x+6=-6

      -6 -6                -6  -6

    -2x=0              -2x= -12   for both equations divide both by two so...

       x=0                  x=6       then check it

45) lí the midpoint of AB is (4,3) and point A has coordinates (-2,6),
sweet [91]
Midpoint has a formula x plus x2 divided by 2 and vice versa for y
So to solve you need to fill in numbers
You can replace x with negative 2 since you know that the coordinates for point A are -2,4
Solve to get 10
And vice versa for the y coordinate you solve the filled in equation to get 0
Your end result is 10,0

Find the zeroes of the polynomial function f(x)=x^4-5x^3+11x^2-25x+30.
katen-ka-za [31]

Step-by-step explanation:

x⁴ − 5x³ + 11x² − 25x + 30

x⁴ − 5x³ + 6x² + 5x² − 25x + 30

x² (x² − 5x + 6) + 5 (x² − 5x + 6)

(x² + 5) (x² − 5x + 6)

(x² + 5) (x − 2) (x −3)

The zeros are 2, 3, and ±√5i.

Suppose you were deciding on a ticket price for a fundraiser dinner. There may be a temptation to continue to raise the ticket s
cestrela7 [59]

Answer:

$50 per ticket.

Step-by-step explanation:

Although it is tempting to keep raising the price for a higher profit, if you raise the price by too much, people will stop buying tickets and you will not gain as much money as you could have gotten with, say, $50 per plate.

The more you raise the price, the less tickets you can sell.

Hope this helps!
